overall review score: 4.3
⭐⭐⭐⭐⭐
score is between 0 and 5
A potentiometer is a three-terminal variable resistor (or voltage divider) used to adjust levels in electronic circuits. It enables manual fine-tuning of voltage or current, commonly found in volume controls, light dimmers, and calibration devices. By rotating a knob or sliding a control, users can vary resistance to achieve the desired effect within an electronic system.
